Pinterest does something really clever related to this - not so much for data placeholder but for images. They have precomputed the dominant color for each image and show that color while the image loads.

That's a really nice detail. I guess it's like the old "progressive" JPEGs from the dialup days, but the lowest level of them (1 pixel).

Oooh, that's a nice site. Gotta add it to my daily reading!

I believe Google images does the same.

Not sure who was first though.

I just checked, and it doesn't look like they do.

They do on the mobile image search at least. Large blocks of the dominant color first, then images load.

Trello does the same
